磁盘组操作, 循环时间, 虚拟磁盘操作限制

循环时间

介质验证操作仅在选定的磁盘组上运行，与其他磁盘组无关。循环时间是指完成验证为其配置了介质验证的磁盘组的元数据区域，以及该磁盘组中的所有虚拟磁盘所花费的时间。磁盘组的下一个循环时间会在当前循环时间完成之后自动开始。可以将介质验证操作的循环时间设置在 1 到 30 天之间。存储控制器会根据循环时间调节对磁盘的介质验证 I/O 访问。

存储阵列在控制器上以独立于其他磁盘组的方式跟踪每个磁盘组的循环时间，并且创建检查点。如果磁盘组上的介质验证操作由磁盘组上的另一个操作优先取代或阻止，则存储阵列会在当前循环结束之后恢复。如果磁盘组上的介质验证进程由于 RAID 控制器模块重新启动而停止，则存储阵列会从上个检查点恢复进程。

虚拟磁盘操作限制

安装在存储阵列中的每个 RAID 控制器模块最多可拥有四个活动的并发虚拟磁盘进程。该限制适用于以下虚拟磁盘进程：

•后台初始化

•前台初始化

•一致性检查

•重建

•回写

如果冗余 RAID 控制器模块在进行现有虚拟磁盘进程时失败，则故障的控制器上的进程会转移至对等控制器。如果对等控制器上已存在四个活动的进程，则会将转移的进程置于暂挂状态。当活动的进程数低于四之后，会在对等控制器上恢复暂挂的进程。

RAID 级别迁移

可以根据需要从一个 RAID 级别迁移至另一个级别。例如，可将容错特性添加至磁条组 (RAID 0)，方法是将它转换为 RAID 5 组。 MDSM 提供有

关 RAID 属性的信息以帮助用户选择适用的 RAID 级别。在系统仍然在运行并且没有重新引导时可执行 RAID 级别迁移，这样可保持数据可用性。

规划：MD3600f 系列存储阵列术语和概念

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
